Transponder Keys Transponder keys (also called chip keys) include an electronic microchip embedded within the head of your car key. The antenna ring of the ignition lock transmits an electronic signal from the key to the computer system of your car when you insert it into the ignition. The chip in your car receives this signal and responds by generating an identification code. This confirms that the key you are using is the right one for your vehicle. The car won't start without this confirmation. This is a relatively new type of anti-theft technology, and it has proven to be effective in deterring theft. Transponder chips are present in all modern cars. The key with a chip usually thicker than the traditional flat keys made of metal and will emit a more powerful electrical signal when it is inserted into the ignition cylinder. You can test the chip by encasing the plastic portion of your key with some tin foil before trying to start the engine. If it doesn't work, the key probably has a transponder in it. Most transponder keys also contain batteries that provide the power required to operate the chip. This battery can break and cause the chip to cease working. When this occurs, your key won't turn the ignition or activate the immobilizer on your vehicle. It is important to replace the battery as soon as you can, if you have a transponder.

The receiver interprets the code and executes the desired action like unlocking the doors or launching the engine. Some key fobs also be used to control other functions, like activating the vehicle's panic alarm system or disarming and arming the security system. The radio frequency (RF) signals used by key fobs are similar to the ones used by cell phones. When the key fob is in the range of a receiver it transmits a small burst of energy, which energizes copper coils on both sides of the device. These coils convert the energy from the radio into electricity, which powers a microcomputer embedded in the fob. The computer transmits a digitalized version of the unique ID number of your car which is later verified by the receiver. Many newer cars are equipped with remote starters which allow you to push the button on a fob to start the engine.
